RIBCL: Get Activation Key?

There's a sample script attached called license.xml. Unfortunately this can only be used to "set" and activation key value. I am trying to true up our advanced pack activation keys and need to query all servers' ilo MPs for the current activation key. According to the ilo MP scripting and command line resource guide, the only parameters available for the LICENSE command within a RIB_INFO block are ACTIVATE and DEACTIVATE. Any undocumented commands or other methods to query these? One contstraint is that I have to go through the OS since many of the iLOs aren't connected to the network (but were when they were activated).
